From your description it sounds like calman does provide a correction matrix. This is not done automatically in HCFR, you have to profile it against a spectrometer or use a correction matrix provided by someone else. You can try the following by manually entering in this matrix (my D3 on Samsung PN51D8000)

Advanced->XYZ coordinates adjustment matrix->Manually edit XYZ conversion matrix
Code:
1.055150     0.008338        -0.013504
0.009191        1.028573        -0.008165
-0.013243       0.020807        0.977213

It won't agree exactly with what calman produces but should be close.

Great - thanks Zoyd - i'll try this and give some feedback!! Cheers again.

from my own experience with color meter , they can behave badly on some display types , and they are not linear , and most of the times, u just don,t get the same reading twice, even u havn,t change any of the setting in your display or in the software, infact if he take another reading with calman, he might just find different reading result even though hes using the same software, unless if he has the OEM version or enhannced then there is a correction file loaded upon connecting to the meter. and even with those correction file/ profiles , the meter still might be off and not reading accurately on your display, because when they make these correction profiles against a reference spectro meter, they do it in their own lab. with their own displays, so yes they can be 100% accurate on their own display and in their own lab. environment elc. but are they realy 100% accurate when we use them at our own display and in our own home? personaly speaking -i don,t think so!
Don,t worry too much about the meter reading as graph can be missleading sometimes , the end result and how the picture looks and what your eyes see is the most important thing.

Thanks to John and others for the reboot on HCFR!

I have an Eyeone LT meter. Other than calibrating it to a known good meter, what will I need in order to use it on a DLP with the new HCFR version?

FWIW, here is the matrix for my D3 which is a D3 "Pro" (Pro meaning it was calibrated by Chromapure) and the corrections were provided, resulting in this matrix. Fairly similar results to yours Zoyd
Code:
1.007784412  0.006564804     -0.002042014
-0.001327602    0.990473662     0.001055968
-0.006456811    0.002961534     1.000986046

Above is "3 color matrix".

If I should use 4 color matrix, it is below.

Hi Marco,

Yes Calman does load a correction file for the i1D Pro both the OEM and retail versions for plasma panels. It is not too dismiliar than the previous profiles mentioned by Zoyd and KJ Garrison.

Calman loads;

X Y Z
x 1 0 0
y 0 1 0
z 0 0 1

Which is equivalent to no correction, right?

We treat the i1 D3 retail and OEM the same because they are. The only difference is one comes with software from x-rite and the other does not.

Ok - so that means there is no corrrection applied to either version's? i was under the impression that u normaly apply correction to all oem meter ....here you go again ndaa75 smile.gif
ndaa75 -how is.t working out for u with the new calibration ? did u try it again ?

You can use a known meter to derive the correction if you have access to one, or as I did, you can purchase a calibrated meter. I got mine with Chromapure, and they provide the correction xy values. Y values are not provided because they say the D3 is very accurate Y.

Ditto on the thanks to JohnAd – great to see this project up and running.

Any word on when we can expect resolution to the i1 pro issues?

Any idea what an i1Display 2 meter is worth? I have a friend who wants to buy mine, and I have no idea what its worth.
post #765 of 3446
I don't seem to be able to install the Argyll drivers. There is no orange triangle in Device Manager. I have used the spyd4en.exe tool and this works fine.
Can you give me an idiot's guide on how to get HCFR to work with Spyder 4 please? I am using version 3.0.4
post #766 of 3446
I just picked up an i1display pro and I've read through the later part of this thread but I still have some questions and want some confirmation on some things. I don't actually have my meter yet, I just want to make sure I have it right before I start. Can someone please correct anything that I have wrong here?:

-The i1display pro is plug and play, no drivers need to be installed.
-To calibrate specific display types, you need to convert the EDR files from the X-rite software/disc to ccss files to unlock them in HCFR.
-To convert EDR files to ccss, you need to run i3dccss.exe in the command line.
-If you don't have the i1 software installed, you can just put the CD-ROM in your drive before running i3dccss.exe and it will locate the files on the disc and convert them.

Now I have a few questions about starting a calibration.

1) I had an i1display LT and I had to calibrate it on a flat black surface before taking measurements and again after ~20 minutes to ensure accuracy. I've read in this thread that you don't need to calibrate the i1display 3/pro, but then later I read that you need to calibrate the meter to sync it or something. Do you have to calibrate the meter before taking measurements or not? And if you do, do you have to re-calibrate it every x minutes?

2) Using the Display 2/LT on a plasma, it was recommended to let the meter warmup resting on the display for ~20-30 minutes before taking measurements. Is this necessary for the i1display pro, or was it only necessary for the 2/LT because of the exposed filters? I'll be using it in contact mode FWIW.

Would really appreciate some help.
Thanks in advance.

Well i tried with Zoyds matrix in both HCFR and Calman and results using his matrix - showed too much red (by approx 10%) compared to Calman standard plasma profile.
Reducing red ave me a better pic!!

Is there support for the Klein K-10 CP, or is it possible to add this meter in a future update?

I'm very intrested in testing the "new" GCD calibration test disc and make an valuation.

You've said previously that Calman is not applying a correction.

That means Calman will tell you red is high but be incorrect. If you can manually enter the correction in Calman the two should agree. All D3s read red low on plasmas by a similar amount which leads to a CCT error of ~500K high. The correction matrix I gave you will get you closer to D65 than no correction at all.

Did you try the two matrices I posted?

I'm very happy that HCFR project is alive!

I use WinXP SP3 laptop to calibrate my LCD TVs and recently I downloaded HCFR v3.0.4.0 and wanted to try it with my Spyder 2 device, but I can't get it working.

When I start HCFR v3.0.4.0 I get this error: "Incorrect driver - Starting communications with the meter failed with severe error. Argyll Error"
But my Spyder 2 works perfectly with ArgyllCMS + dispcalGUI, but not with HCFR v3.0.4.0.

Any advice how to solve this problem?

Bytec, I have exactly the same problem with Spyder 4 and would much appreciate anyone's help on this.
post #773 of 3446
John, Zoyd or anyone knowing this.

first of all I am a bit late on this but here goes

I got a i1d3 Pro from Chromapure and want to use the corrections given by chromapure. assuming that the correction matrix on page 22 is the correct one (would it be worth putting the link in the first post?) do I use the 3 or 4 color matrix?

also is my report from chromapure look like this ProMeterReport.pdf 49k .pdf file is this usable?

at last of all asumming I can use the report aove how do i enter the matrix in HFCR? Sensor preferences ->sensor matrix? Do i not enter anything in the calibration tab?

Enter in the reference and meter (field) x,y values from the report, and then use the 4-color matrix results from the metercorrection spreadsheet John provided. Enter that matrix in HCFR under Advanced->XYZ coordinates adjustment matrix->Manually edit XYZ conversion matrix. After that you will notice that the XYZ adjustment box in "Parameters" is automatically checked and active.

run the calibration to sync the D3 to the plasma refresh rate before starting (just need to do once). no warm-up time or recalibration is needed, the probe automatically corrects for dark current drift.
post #777 of 3446
Thanks zoyd.
post #778 of 3446
I just have a few more questions.

Refresh mode should only be used on plasma & CRT - Non-Refresh mode for the rest?
Calibrate the meter once before you start on any disply, however this is very important on Plasma?

Is the calibration matrix i used from the Chromapure report not more acurate then the generic files created by running the i1d3ccss.exe tool? and if so do I need to run the tool (my meter is an OEM meter so I dont have the disk, however if required I could borrow one.

Thank you
post #779 of 3446
Thread Starter 
yes, refresh mode is for Plasma/CRT only - I don't think it matters if you dark calibrate or not for non-refresh mode but it won't hurt. The Chromapure correction will be more accurate than the generic profiles because it's based on your meter, not a generic display correction.
post #780 of 3446
I am new to calibration so please bare with me. I read conflicting information on whether the new colormunki display will work with HCFR. Can somome please confirm? A few have asked this but there's been no answer. The reason its confusing is because there are retail and OEM versions. The HCFR site mentions that the latest software supports it but I would hate to buy the wrong munki and not have it work. Similarly, is any version of the PRO guarnateed to work? Thanks !
